Though some teams around the country suffered setbacks last week, most of the Perfect Game College Top 25 reaped the benefits of impressive play.

North Carolina had another successful weekend, taking two of three from Miami at home. The Tar Heels remain the nation's top-ranked team, while the top five remains the same with Vanderbilt, LSU, UCLA and Oregon State as headliners.

There were no changes in the top 12 of this week's rankings, while Arizona State dropped from No. 13 to No. 18 following a disappointing home series against Washington State, and Arkansas dropped from No. 16 to No. 22 following a tough home series loss to Mississippi.

Virginia was the big mover this week. There had been questions about the Cavaliers because of their rather weak non-conference schedule. However, they hit the road to Clemson over the weekend and captured an impressive ACC series win. With the victory, the Cavaliers vaulted from No. 22 to No. 14.

Also worth noting, Notre Dame moved from No. 17 to No. 15 after earning a solid series win over Cal Poly over the weekend, while Oregon had a successful trip down to USC and gained some ground, going from No. 19 to No. 16.

Arizona and UNLV dropped out of this week's rankings following tough series losses to Oregon State and New Mexico, respectively, while Indiana and Virginia Tech are the beneficiaries.

The Hoosiers are off to a hot start this season and have some nice wins under their belt, while despite a tough series loss to Georgia Tech two weekends ago, the Hokies responded in impressive fashion over the weekend with a road series sweep over Duke with starting pitcher Joe Mantiply returning to the rotation.
